, aw whom it may concern.-

, Be it known that I, MAX KLEMM, a subject of the German Em eror, residing at Bielefeld, in the Empire of ermany, have invented a certain new Automatic Lubricator, of which the following is a specification.

- The invention relates to improvements in automatic lubricating devices, and is espe- .cially adapted for power-transmission mechanisms employing chains v and sprocketwheels. I

The invention consists in the provision of a source of sup ly for-the lubricant, which is so arranged wit respect to the part lubricated as to provide a gravity-feed, devices 'being employed which cooperate with movable parts of the transmission mechanism, preferably the s rocket-wheel in such a manner as 'to c ontro the feed of the lubricant and cause intermittent delivery thereof.

The inventionwill be more fully described in connection with the accompanying drawings and will be more particularl pointed out and ascertained in and by t e appended claim.

In the drawings, Fi ure 1 is a side elevation of an automatic ubricator embodying the main features of my invention. Fig. 2 is a front elevation thereof with parts in sectron.

Like characters of reference desilgnate similar parts in the different figures o the drawmgs.

- -As shown, a designates a'source of supply for the lubricant, which in the present con struction consists of a closable receptacle. A pipe 0, leading from the bottom of said rece tacle, is provided between its ends with a va ve j; carrying a slotted arm f. A link It connects sai arm with a swing-arm e, pivoted at e in any suitable manner to a convenient stationar part, which, as shown, consists of a sup ort Said arme is made in two parts, w 'ch, as shown, are adjustabl connected at e in orderto lengthen or s orte'n said arm and vary the delivery of the lubri-' cant, as will hereinafter more fully appear.

The lower end of said arm e carries an elongated engaging portion 0 which projects into the. path of and is adapted to be engaged by the teeth of the sprocket-wheel I. In order to normnlly maintain the valve f in.a

closed position, provide a contractile spring g, which is connected at one end with the arm may be secured to any stationary part of the device, such as the support 6.

Between the receptacle (1 and the valve f the pipe 0 is provided with a valve (2, which under control of the devices effecting inter when it is desired to throw the arm e out of engagement with the wheel I' it will merely be necessary to shorten the same, so that it will notproject into the path of the teeth of said wheel. I

It will be obvious from the foregoing that as the wheel I rotates the teeth will engage the right, serving to open the valve f, and that spring 9 willreturn the same to a retracted position and close-the valve f, thereby eiiectadjust ng devices rovided permit notkonly the adjustment of t e armeto vary the iength of time which the valve f is open, but the slotted and ad'ustable connection of the valve-arm f an link It affords additional justing means, whereby the degree of open ing of the valve may be varied.

7 claim- An improved lubricating apparatus com ubricant, a pipe leading therefrom, a valve in said pipe adapted to permanently close or open the same, a second valve in said'p-ipe in presence of two witnesses. MAX KLEMM.
